Awesome pictures! It looks like a really beautiful place to visit. I don't know if I could manage walking with all of those hills let alone run. That is pretty crazy. The castle wall is probably my favorite picture. Is it just for show or was there really a castle there at one time?
I suspect it's more modern than it looks. There were some seriously wealthy people there who could afford such novelties
I wondered, because the upper part of it looked in pretty good shape, but the foundation part of it looked like it could have been original.
